. 13 Claims, 3 Drawing Figures 1 DETACHABLE WRECKING DEVICE This invention relates to tools for use with tractors and, more particularly, to implements which may be conveniently attached to the front ofa bucket loader or bulldozer and used to wreck small buildings.

In the business of wrecking small buildings, it is highly desirable that any individual building be wrecked 'as cheaply as possible, i.e. both rapidly and using a minimum number of men and machines. In order to wreck relatively small buildings, say two to four stories high of brick or wood frame construction, ti has in the past often been found necessary to use two separate machines, one, such as a crane with a heavy ball swinging from it, to demolish the building, andthe other, such as a bucket loader, to load the resultant debris onto trucks to be hauled away. Using separate machines for the demolition and loading operations increased the per unit cost of building wrecking because of the increased cost of operating two machines rather than one, the necessity to hire men skilled in operating two separate types of machines, and the logistic problem of having to have two machines at the demolition' site rather than one. These problems are particularly acute to the small, independentwrecking contractor. It has thus been found desirable to develop a machine capable of performing both the the demolition and loading steps.

SUMMARY This-invention provides a detachable implement for use with a bucket loader, bulldozer, or similar tractor-driven machine which may be used for demolishing small buildings. It comprises an elongateboom' assembly for attachment to the bucket or blade at one end thereof and a tool assembly attached to-the other end and including a tool support and a tool head. The tool assembly is, preferably, capable of being extended from the boom assembly so that the length of the implement may be adjusted. Support means may also be provided within the bucket or blade to strengthen it while the implement is in use. p 1

Accordingly, it is an object of this invention to provide an implement for use with tractor-driven machines that may be used to wreck small buildings.

It is an object of this invention to provide such an implement which may easily be attached to and detached from the machine.

It is an object of this invention to provide such an implement which has an easily adjustable length.

It is an object of this invention to provide .such an implement which includes means for strengthening the bucket or blade to which it is attached.

It is an object of this invention to provide such an implement which is characterized by simplicity of design and ease of construction.

DESCRIPTION OF THE DRAWING FIG. 1 is a side view of an implement incorporating one embodiment of this invention attached to a tractor-driven bucket loader;

may be hollow having interior dimensions slightly greater than the exterior dimensions'of support beam 14 so that it may slidably receive the tool support beam. Tool support beam 14 may have a series of regularly spaced adjusting holes (not shown) diametrically therethrough while lower-boom 20 has a mating hole (not shown) diametrically therethrough. A lock bolt 24 is placed through the mating hole and the adjusting hole with which it is aligned and secured in place by a lock nut 28. It will be seen that the overall length of implement 10 may be varied by sliding tool support beam 14 in and out of lower boom 20 until one of the adjusting holes is aligned with the mating hole. Placing lock bolt 24 through the aligned holes and securing it with lock nut 28 then secures the tool assembly of tool head 12 and tool support beam 14 in place. Alternatively, the implement might be lengthened by similarly adding extension sections between lower boom 20 and tool support beam 14. I

A- hollow upper boom 30 is attached to lower boom 20 at a pivot joint 32, which is preferably such that upper boom 30 may be folded down against lower boom 20 when the implement is not in use for ease of transportation and storage. A spreader 34 is connected to lower boom 20 and upper boom 30 at a point approximately midway between pivot joint 32 and the end of implement l0 opposite tool head 12. The

means of connection, as by bolting, is preferably such that spreader 34 may be easily moved to allow upper boom 30 to rotatetowardslower boom 20 when the implement is not in FIG. 2 is a pictorial, detail view of the implement of FIG. I,

showing how it is attached to the bucket loader; and

FIG. 3 is a cross section view taken along the line 3-3 of FIG. 2 showing in detail the jack and attachment brackets of the embodiment of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT ment shown, the tool head is in the form of a pick and has two blades 16 and 18 attached to opposite ends thereof. Tool sup port beam I4 is attached to a lower boom 20. The lower boom use. When the spreader is positioned as shown, it aids in maintaining the upper and lower booms in a fixed relationship.

A lower attachment bracket 36 is connected to lower boom 30 at the end thereof opposite tool head 12 forattaching the lower boom to the lower side of a bucket 38 which is part of a bucket loader 40 driven by a tractor 42 in the conventional manner. Any similar tractor-driven operative instrument might be substituted for the bucket.'The bracket has a boom plate 44, shown dashed in FIG. 3, extending into and fixedly attached to as by'bolting, as shown, or welding, hollow boom 20, a cover plate 46 perpendicular to the boom plate extending over the end of the boom-and attached thereto, and a bucket plate 48 extending obliquely from the boom and cover plates. Bucket plate 48 has a hole, not shown, therethrough which-aligns with a hole through the lower side of bucket 38, also not shown. A bolt 50 extends through those holes andis secured by a nut 52 thus attaching lower boom 20 to bucket 38.

An upper attachment bracket 54, similar to lower attachment bracket 36, connects the end of upper boom 30 to the upper side of bucket 38. The upper bracket has a boom plate 56, shown dashed in FIG. 3, extending into'and fixedly attached to upper boom 30, a cover plate 58 perpendicular to the boom plate extending over the boom andfixedly attached thereto, and a bucket plate 60 extending obliquely from the boom and cover plates. Bucket plate 60 has a hole, not shown, therethrough which aligns with a hole through the upper side of bucket 38, also not shown. A bolt 62 extends through those two holes and is secured by a nut 64 thus attaching upper boom 30 to bucket 38.'Bolts 66 and 68 and nuts 70 and 72 may cooperate with holes through upper boom 30 and boom plate 56 to attach the boom plate to the boom.

A turnbuckle jack 74 is placed between the upper and lower sides'of bucket 38 to keep the bucket from collapsing under the loads imposed by implement 10. It is comprised of a loop 76 to which tow support rods 78 and 80 are threadably attached. An upper jack plate 82 is rotatably affixed to support rod, 78, as by bolts 84 and 86, and a lower jack plate is rotatably affixed to support rod 80. The jack 74 is placed between lower attachment bracket 36 and the top of bucket 38 when the implement is attached to the bucket and expanded by turning loop 76. The jack may be attached to the attachment bracket by nuts 92 and 94 and bolts 96 and 98 through corresponding holes in lower jack plate 90, boom plate 44, and the lower boom 20 and to the upper side of bucket 38 by nut 62 and bolt 64 through a corresponding hole in upper jack plate 82.

A guideline 100 is connected between one side of the bucket and lower boom 20 to restrain lateral movement of the implement. A pin joint 102 is provided on the side of the boom with a pin 104 passing through an eye at one extremity of guide line 100. A shackle 106 is attached to the other extremity of guideline 100 and is placed through a hole in the side of bucket 38. A pin 108 through the shackle may be easily removed so that the guide line may be disconnected from the bucket when the implement is removed. A similar guideline 110 is provided on the other side of the implement.

It will be obvious that certain modifications of the specific embodiment described above may be made without departing from the spirit and scope of this invention. For example, the arrangement of the boom might be altered, different means might be used for attaching the boom to the bucket, or the implement might be used on the blade of a bulldozer rather than on the bucket of a bucket loader.

It will thus be seen that a wrecking implement has been provided which fulfills all of the above-mentioned objects. In particular, it may be easily affixed to or detached from bucket 38 by inserting or removing bolts 50 and 62 and connecting or disconnecting guide line 100 and 110. Moreover, it may be collapsed for easy transportation by removing spreader 34 and jack 74. While a particular embodiment of this invention is disclosed above, it will be understood, of course, that the in-' vention is not to be limited thereto since many modifications may be made. It is contemplated, therefore, by the appended claims to cover any such modifications as fall within the true spirit and scope of this invention.
